Introduction

be quiet! renewed its affordable System Power series, and the new models have increased capacities and a different OEM for the models up to 750 W. The 450 W up to 750 W units are Bronze rated, while the flagship System Power 10 model with 850 W max power is rated as Gold since it uses a different platform from the rest. Its price is also notably higher. The System Power 10 750 W, which I evaluate in this review, has a retail price of $75, while the 850 W model goes for $110.

All System Power 10 units use a non-modular cable design to reduce production costs. The OEM for the 450 - 750 W units is HEC, and the platform is an older design using some newer elements, including DC-DC converters for the generation of the minor rails. All line members operate with 200 - 240 VAC input, so they are destined for the 230 V markets only, and not for the US. Compared to the previous models, the new ones (from 450 to 750 W) have 50 W more for every model tier, are compatible with alternative sleep modes, use flat (ribbon cables) instead of sleeved ones, have a single rail instead of two, and the warranty has been increased to five years from three. A warranty increase always looks nice to users since it is evidence of increased reliability. The similarities between the 450 W to 750 W models and the older generation System Power 9 units are the PSU's housing and the fan, which remain the same. It would be great if be quiet! replaced the fan with a higher quality one.

The System Power 10 750 is 80 Plus and Cybenetics Bronze rated, and in noise, it gets a Cybenetics Standard++ which is decent for a bronze unit of this capacity. Still, given the brand's name, I expected better in the noise output section. This is an affordable PSU, and its main competitors are the XPG Pylon 750, the Thermaltake Smart BM2 750, and the Corsair CX750M. In the EU market, there is also the Chieftronic SteelPower 750. All three PSUs mentioned above use Channel Well Technology's (CWT) platforms.
